Digital Tools for Teachers is an ebook by Nik Peachey. Aimed at English language teachers, it includes over 70 tools – divided into reading tools, writing tools, presentation tools, etc.
For example, under Reading Tools there is a review of Rewordify and under Listening Tools you can find LyricsTraining.
The book is in PDF format, I couldn’t get the internal links (to the various chapters) to work, but the links to the tools were fine.
You can read more about the book. It costs $4.99, but there is a code you can use to download it for free.
